Surgical Stress Measured by Microdialysis

Paraspinal muscle damage is inevitable during conventional posterior lumbar fusion surgery. Minimal invasive surgery is postulated to result in less muscle damage and better outcome. The aim of this study is to monitor metabolic changes of the paraspinal muscle and to evaluate paraspinal muscle damage during surgery using microdialysis (MD).

About this study

Posterior approach is a common and important surgical procedure for various lumbar diseases. Owing to the anatomy, the damage of paraspinal muscle is inevitable during conventional posterior lumbar fusion surgery. Degeneration and malfunction of the paraspinal muscle might associate with pain and inferior postoperative clinical outcome.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • patients who undergo conventional instrumented posterolateral lumbar fusion.

Exclusion criteria

  • previous fusion
  • chronic metabolic disease
  • tumor or metastasis
  • postoperative surgical complications and complications during surgery

Treatment and study plan

Posterolateral lumbar fusion surgery

Procedure

Two MD catheters with 1% lidocaine 1-2 ml are placed in the paraspinal muscle.

Other names: Lumbar diseases

Primary outcomes

  1. The glycerol concentration

    Time frame: Two hours

    To study whether the glucerol concentration can be used to evaluate surgery related paraspinal muscle damage
